Toughener series-polyester class
Thermoplastic polyester toughener (GT-RE, GT-REN)
Product Description
This series of products is a special toughener developed for PBT and PET by Xingete. This series of tougheners are acrylate and glycidyl ester difunctional ethylene elastomers, which are widely used in the strengthening and toughening, flame retardant, and toughening of polyester products, etc. The product improves the impact strength and elongation of engineering plastics.
Typical Use
- Glass fiber reinforced and toughened PBT, PET。
- Reinforced and toughened the flame retardant PBT, PET。
Product Features
- Improve the processing performance of thermoplastic polyesters
- Improve impact strength
- Improve dimensional stability
Recommended dosage
- The appropriate ratio can be selected according to specific application requirements. The recommended dosage is 3%~10%。
Instructions
- Granulate after uniform mixing with polyester resin
Packaging and Storage
- Use kraft paper bag lined with plastic bag for packaging. The net weight of each bag is 25Kg. It can be stored and transported under dry conditions as non-dangerous goods. Avoid sunlight and water.
